METALLIC BEDSTEAD.

SPECIFICATION forming part of Letters Patent N 0. 782,981, dated February 21, 1905. Application filed July 25, 1904. Serial No. 218,121.

To all whom, it may concern:

Be it known that I, MICHEL MoHR, a citizen of the United States, residing at VVahpeton, in the county of Richland and State of North Dakota. have invented certain new and useful Improvements in Metal Bedsteads, of which the following is a specification.

My invention relates to improvements in bedsteads, and has for its object an improved construction and means for assembling the frames of iron bedsteads whereby a strong connection is effected at the four corners of the bedstead. Additional strength is secured at the joints by having the connected elements interlocked with each other, so that each member of the joint will aid in maintaining the joint rigid, and a construction is provided which while rigid and strong when assembled will be easy to assemble and take down. The separate parts of the joint are so fashioned that the appearance presented will be neat and simple and the joint will be compact and strong, but comparatively cheap in first cost.

The invention consists in the novel features of construction, combinations, and arrangements of parts, as hereinafter described in the specification, more particularly pointed out in the claims,and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a bedstead embodying the present invention. Fig. 2 is a top plan view of one of the corner-joints of the bedstead. Fig. 3 is an inside elevation of the joint, showing a broken side bar, the end bar being removed. one member ofthe joint, showing a part of an end bar, the side bar being removed. Fig. 5 is a top view of one end of an end bar, the other end being duplicated. Figs. 6 and 7 are bottom views of the joint sectional castings detached; and Fig. 8 is a central vertical section of a joint, showing one end of a side bar in elevation.

The frame of the bedstead consists of two side bars 1 1, the two end bars 2 2, and the sectional castings 3 and 4. The sections 4 of the castings each are provided with an opening 5 for the-reception of the posts 6 of the bedstead, as is usual.

Fig. 4 is an elevation of The two sections 3 and 40f the casting are firmly secured together by a mortise 4 in the casting or block 4 and a tenon 3 on the casting 3. Said mortise and tenon are preferably fashioned to have a tapered fitand when firmly wedged provide a secure joint between the castings. The tapering fit to the mortise and tenon may be dispensed with and other means provided for holding the castings in vertical engagement, although the described construc: tion is considered preferable.

The side bars 1 and end bars 2 are L-shaped in cross-section, and the castings 3 and 4 are respectively provided with slots 7 and 8 of the same formation and adapted to receive the ends of said bars. These slots 7'and 8 extend entirely through the castings 3 and 4. The

' slot 7 passes through the casting 3 and through its tenon 3 but the formation of the slot is altered within a short distance of the entrance to the slot, as the bar 1 is reduced in size in the slot and only the vertical portion 1 of the bar passes entirely through the slot of casting 3 and its tenon 3, shoulders 1 and 1 being formed on the bar 1, which shoulders bear against recesses formed at the entrance to the slot 7.

The casting or section 4 has the L-shaped slot 8 therein to receive the end of the end bar 2 of the bedstead. Said bars 2 near each end are provided with a circular opening or cutaway portion 9 of a diameter approximating that of the tenon 3 at its vertical center or large enough to permit the passage there- 'through of the tenon to about its median tapered thickness or diameter. WVhen said bar 2 is inserted in the slot 8 in casting 4, it is passed to the opposite side of the casting, and its end is flush with the outer wall of the casting, and the opening 9 becomes a part of the inortise 4.

The operation of assembling the parts will be evident from an inspection of the drawings. The bars 2 are inserted in the slots 8 of block 4, bars 1 are inserted in their corresponding slots 7 of the casting 3, the tapered tenon is entered into its correspondingly-tapered mortise, and the two castings 3 and 4, with their end bars, are locked together in a firm and secure manner. The end bars 2 are locked by the mortise-and-tenon joint as the tenon passes through opening 9 therein with a neat fit and securely and firmly holds the end bars from endwise movement as well as vertical movement.

The length of the slot 7 in which the end 1 of bar 1 is inserted, together with the close fit of the shoulders 1 and 1 in their respective recesses, insures a rigid and stable connection, and as the mortise and tenon prevent an endwise separation of the frame of the bedstead said joint cannot be detached.

It will be noted that the end of portion 1 of bar 1 is beveled to rest against the inclined wall of the tapered mortise 4 and the opening 9 in bar 2.

From the foregoing description, taken in connection with the accompanying drawings, it is obvious that 1 have produced a construction which fulfils all the conditions set forth as the purpose or object of my invention. By providing the castings with slots or seats extending entirely through them a strong connection is secured, and each casting, as well as the entire assembled joint, is strengthened and braced by having the side and end bars pass entirely through said castings, and as the elements are susceptible of a neat and close fit a practically solid joint is formed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a bedstead, the combination with a sectional casting and a slot through one of said castings or sections, of a bar entered in said slot and having means for engagement with a device on the other section for locking the elements.

2. In a bedstead a casting having a mortise therein, a second casting having a tenon thereon, a slot through the first casting and a bar having means for engagement with said tenon located in said slot.

3. In a bedstead a casting having atapering mortise therein, a second casting having atapering tenon, aslot through the mortised casting, and a bar located in said slot having means for engagement with said tenon.

4. In a bedstead, the combination with a sectional casting and a slot through one of said sections, an end bar entered into said slot and having means for engagement with the, other section when said sections are locked together.

5. In a bedstead, the combination with asectional casting, an L-shaped slot through one of said sections, a bar L-shaped in cross-seetion located in said slot and extending therethrough, and means on the other section for engagement with said bar.

6. A bar L -shaped in cross-section and forming an element of a bedstead-frame, said bar having cut-away portions near its ends for engagement with means located within the joints of the frame for locking said frame.

7. In a bedstead, the combination with a sectional casting, a slot extending lengthwise through one of said castings, said slot having a reduced portion, a bar L- shaped in crosssection having a reduced end to fit said slot, and means for locking said castings together.

8. In a bedstead, the combination with a seetional casting, a tenon on one of said castings, aslot extending through said casting and tenon and having a reduced portion, a bar L-shaped in cross-section having a reduced end to fitsaid slot, and a mortise in the other section adapted to receive said tenon.

9. In a bedstead a casting having a mortise therein and a slot extending through said casting, a bar located in said slot; a second casting provided with a tenon and having a slot extending through said casting, a bar located in said slot; and means on the bar in the mortised casting for engagement with said tenon.

10. In a bedstead a casting having a mortise therein and a slot extending through said casting, a bar L-shaped in cross-section located in said slot; a second casting, a tenon therea on, and a slot through said casting and tenon,

a bar L-shaped in cross-section having a reduced end and shoulders adapted to fit said slot, and means on the bar in the mortised casting for engagement with said tenon.

11. In a bedstead-joint, a casting having a mortise therein and a slot extending through said casting, a bar L-shaped in cross-section extending through said slot, a cut-away portion in the bar; a second casting, atenon thereon and a slot through said casting and tenon, and a bar L-shaped in cross-section having a reduced end portion and shoulders thereon adapted to fit said slot, said tenon passing through the cut-away portion of the bar in the mortised casting to lock the same.

In testimony whereof I affix my signature in presence of two witnesses.
